Which line is parallel to a line that has a slope of 3 and a y-intercept at (0,0)?

Answer:
y = 3x
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
• Parallel lines have equal slopes, hence
The slope m = 3
Since the line passes through (0, 0) ⇒ c = 0, thus
y = 3x ← equation of parallel line
Answer:
y = 3x
Step-by-step explanation:
slope of line = 3
passing through = (0, 0)
The equation of line passing through a point and the slope is given is
[tex]y-y_{1}=m\left ( x-x_{1} \right )[/tex]
y - 0 = 3 (x - 0)
y = 3 x
Thus, the equation of line is given by y = 3 x.
